Title: Electrophotographic copying machine with automatic paper selecting function
Inventor: ITO MASAZUMI
IPC: B65H7/04
Filed: 1986-03-10
Abstract: PURPOSE:To replenish paper and to improve the operativity of copying operation by permitting a start when there is paper which is selected possible at another paper feed slot, and informing that the paper is absent before the start when not. CONSTITUTION:A control means is provided which retrieves the states of other paper feed slots by a paper detecting means even if the paper detecting means judges that there is no paper at the currently selected paper feed slot when a mode wherein an automatic paper selecting means is put in operation is selected by an operating means. This means allows the start of copying operation without starting a resetting means on condition that there is even one paper feed slot where usable paper determined by copy magnification selected by a magnification input means is set, decides the best paper from the copy magnification and original size when the size of an original is detected by an original size detecting means, and searches for a paper feed slot where the best paper is set among other paper feed slots, thus selecting the paper feed slot.

Title: Two-dimensional forecast dpcm decoding device
Inventor: HAMADA HIROYUKI
IPC: H04N19/423
Filed: 1989-03-07
Abstract: PURPOSE:To prevent forecasting using the data of a broken line by forecasting by using the data preceding by two lines of strong correlation to the data preceding by one line as substitute for the erroneous data preceding by one line. CONSTITUTION:A packet separator 1 detects the omission of a packet, and outputs a packet omission signal. Since this detection signal causes the delay of one line portion at its maximum behind input data, the input date is delayed by providing a 1H delay circuit 2. On the arrival of the detection signal, a switch 14 turns to a contact (b) side, and preceding line data in the delay circuit 6 is outputted as it is. When there is no packet omission in a next line, the switch 14 returns to a contact (a) side, and usual decoding operation is executed. Said line is interpolated by the preceding line, and the next line can be forecast from an interpolated line, and the deterioration of picture quality due to a burst error can be prevented.

Title: Method for detecting positional deviation and gap
Inventor: KATO KATSUHIRO
IPC: G01D5/36
Filed: 1993-02-22
Abstract: PURPOSE:To provide a method for detecting positional deviation by which an in-plane positional deviation can be detected and, at the same time, the gap between two objects can be directly, stably, and continuously measured even when the objects are exposed to light. CONSTITUTION:Two sets of two monochromic luminous fluxes f1 and f2 having slightly different frequencies (namely, four luminous fluxes) are used. The two luminous fluxes of each set are respectively made incident to a mask M and the diffraction gratings 32a and 32b of a waver W at incident angles theta1 and theta2, (theta1<theta2) on one side of the optical axis of an objective lens 31 so that the incident directions of the luminous fluxes of one set can become right-left reversely symmetrical to those of the luminous fluxes of the other set with respect to the optical axis. The displacement of the mask M and wafer W is found by fetching optical heterodyne-interference diffracted light rays of four or more beams from symmetrical positions on both sides of the optical axis and separately calculating the two-dimensional phase variation in both X- and Z-directions from the phase of optical heterodyne detecting signals generated in accordance with the variation of optical path difference resulting from the positional deviations of the gratings 32a and 32b in both the X-and Z-directions.
